    DMV 4020 ATC not working intermittently.

    We have a Daewoo DMV 4020 w/ a armless automatic tool changer. The tool changer will work fine one minute then stop at the m33 line and not move from the parked pos. . When I check continuity of the limit switches both of them are closed "made". When it is working right both switches work right, one open one closed. any help would be super helpful. Thank you in advance.

    Hello. Did you manage to fix the error? Do you have documentation for the machine?
